This issue will not be resolved in GCC 4.1.0; retargeted at GCC 4.1.1.

I don't quite understand how likely we are to see this ICE; -Os
-ftree-loop-linear seems like an obscure combination of flags.  I'll call it P2
for now.

I think the reason why this ICE occurs with my patch
(http://gcc.gnu.org/viewcvs?view=revrev=102356) is that my patch enables
data-refs analysis for INDIRECT_REFs. Similar ICE in PR 20256 happens also
before my patch since the data-refs there are ARRAY_REFs, and ARRAY_REFs were
already supported before.
